Yahoo’s new web portal goes live

 

Internet giant Yahoo has relaunched its web portal, supported by a $100m global advertising campaign.

 

The new front page makes room for content and services from rivals

The company hopes the website refresh will boost both traffic and revenues.

Yahoo will also open its home page to rivals, allowing users to integrate third-party web services like Facebook or Hotmail into its portal.

Yahoo has been struggling to turn its position as the world’s most popular website into profits. The portal is the first move of new boss Carol Bartz.

Rich Riley says, “Yahoo can remain at the centre of the web experience”

The new portal, however, also has an unprecedented number of links to non-Yahoo websites, potentially taking traffic away from Yahoo’s sprawling network of news, weather, finance, email, messaging, and picture services and more.

In the UK, for example, the Yahoo website features top headlines from the Telegraph, Guardian and Daily Mail newspapers.

Since the beta version of the Yahoo website was launched in the UK, Yahoo has become the second-largest source of online traffic to the Telegraph’s website, said Mr Riley.

Yahoo is getting a share of the advertising revenue generated by this traffic to partners. Read more…

Aussie Scientists Pack Massive Data Onto Single 5-D Discs

Aussies develop multi-terabyte optical storage…

Researchers at a University in Melbourne, Australia have come up with a “five dimensional” disc capable of storing 2,000 times more data than a conventional DVD.

That’s 10TB per DVD disc, in case you’re counting.

The research was conducted in Centre of Micro-Photonics at Swinburne University and was in the journal Nature.

Friday, May 22, 2009: For the first time, researchers from the University’s Centre for Micro-Photonics have demonstrated how nanotechnology can enable the creation of ‘five dimensional’ discs with huge storage capacities. Their findings point towards using nanoscopic particles to exponentially boost the amount of information stored on a single disc with a unique ‘five dimensional’ structure.

The discs are the same size as a conventional three dimensional existing DVDs.

This means that data – usually written in a typical three dimensional (x, y, z) fashion – acquired two more dimensions. So far this has already resulted in an optical disc sample capable of storing 1.6TB of data, but as development continues, researchers Min Gu, Peter Zijlstra and James Won expect storage capacity to reach a whopping 10TB.

 

We were able to show how nanostructured material can be incorporated onto a disc in order to increase data capacity, without increasing the physical size of the disc,” said Professor Min Gu, one of the researchers on the team.

The research, carried out by Peter Zijlstra, Dr James Chon and Professor Min Gu was published in the scientific journal Nature. The Nature article describes how the researchers were able to use nanoscopic particles to exponentially increase the amount of information contained on a single disc.

Discs currently have three spatial dimensions, but using nanoparticles the Swinburne researchers were able to introduce a spectral – or colour – dimension as well as a polarisation dimension.

 

“These extra dimensions are the key to creating ultra-high capacity discs,” Gu said.

 
To fabricate the ‘color dimension’, gold nanorods are interleaved into the disc’s surface. The information can then be recorded in a range of different color wavelengths on the same physical disc location. This is possible due to a unique characteristic of the nanoparticles, which react differently to light depending on their shape.

This is a major improvement on current DVDs that are recorded in a single colour wavelength using a laser.

None of these techniques are actually new, just the fact that they were all applied at the same time. This brings about at least one major problem that the technology has to contend with, that is, recording speed. Current prototypes record about as fast as a glyph-carver in ancient Egypt, the researchers have implied.

Another problem such high-capacity media are going to have to confront is tied up with several related terms like robustness, reliability and longevity. At least initially, most people will want to have such large capacity physical media offer some assurance that they won’t self-destruct within merely five or fifteen years as most presently available CD and DVD discs are all too prone to do.

But we guess the scientists are working on first things first, thinking about how to do this before working out how to make people believe it’s worth entrusting lots of valuable data to it.

The discs are likely to have immediate applications in a range of fields. They would be valuable for storing extremely large medical files such as MRIs and could also provide a boon in the financial, military and security arenas.

Yahoo Search Adds New Features

Yahoo Search Adds New Features, Search Pad, works as an online personal research assistant.

Since most people now conduct their research on the Internet, they will benefit from tools that help them organize their searches.
 
 

Friday, July 10, 2009:
Yahoo! has announced a new Search feature that lets people capture, organise, save and share information they find while researching online. Search Pad provides a new search experience that is especially valuable for people conducting extensive research in categories such as academic, health, jobs, travel or shopping, says the company.

Search Pad automatically recognizes when people are conducting research and allow them to capture information and websites found in their search results. Once activated, Search Pad automatically saves recent items, including links in one integrated notepad that stays with them as they search. People can edit their notes and then print, save, email or share their Search Pad documents with family, friends, colleagues or anyone else, eliminating the need for others to do the same research.
 

Yahoo! Search Pad Preview…


 

About this upgrade Larry Cornett, vice president, consumer products, Yahoo! Search said,

“At Yahoo! Search, we are committed to understanding people’s intent and building the right tools to help them complete their most important tasks online.”

he also added, “With Search Pad, Yahoo! is providing an elegant solution that understands when valuable research is being conducted and offers a way to effortlessly gather information in one place. Yahoo! Search Pad helps people make decisions, save their work and share the best with friends and colleagues.”

Available on Yahoo! Search, Search Pad features automatic research detection; and Simple Collecting — integrated into the search experience; once research begins, it automatically collects visited websites and thumbnails.

We can do much more than just keep notes as well in Search Pad. After enabling the feature, you can e-dit, reorder and delete unwanted entries. All of your information can be saved by logging in with your Yahoo ID. You can also print out the collected data or send an email with the relevant information.
